SAKIGHI TOYODA, OF SHIMASAKI-CHO, NAGOYA, JAPAN.

PROTECTING MEANS FOR SHUTTLE-REPLENISI-IING- DEVICES.

To all whom it may concern Be it known that I, SAKICHI TOYODA, a subject of the Emperor of Japan, residing at Shimasaki-cho, Nagoya, in the Empire of Japan, have invented a certain new and useful Improvement in Protecting Means for Shuttle-Replenishing Devices; and I do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement.

This invention relates to looms and has special reference to a protector mechanism for such devices.

One object of the invention is to improve and simplify the general construction of protector devices for looms.

A second object of the invention is to pro vide a stop motion of improved form, which will stop the action of the loom in case the shuttle is not thrown fully into the box at the receiving ends.

With the above and other objects in view the invention consists in general of certain novel features of construction, and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

Figure 1 is an end elevation of a loom showing the application of my invention thereto, certain of the parts being broken away and other parts being shown in sections are omitted in order to show a section of the shuttle box at the far side of the loom. Fig. 2 is a rear view of the 100111 as constructed in accordance with my invention.

Like characters of reference designate similar parts throughout the diflerent figures of the drawings.

First referring to F ig. 1, 1 designates the frame of the loom, and 2 designates a rock shaft mounted in said frame and adapted to support the lay swords 3 and the picker stick or bar 1. The lay swords are provided with hubs 5 by means of which they are mounted upon the rock shaft 2, and a bearing 6, mounted on the rock shaft 2, is pivotally connected at 7 with the picker bar 4. A spring 8 is connected at 9 with the picker bar and at 10 with one of the lay swords. with a support 12 on which a lever 13 is pivotally mounted. The lever 13 is provided with a cam shaped portion which comprises a downwardly inclined part 14, which is up- Speeification of Letters'latent.

The picker check 11 is provided.

wardly inclined at 15, and may have a substantially horizontal extension 16. The picker bar a may be provided with a roller 17 adapted to engage this cam-shaped port1on to operate the lever 13, for purposes which will hereinafter more fully appear.

On the front sides of the lay swords 3 are bearings 22 in which a rock shaft 23 is mounted. The rock shaft 23 carries at its opposite ends daggers 2a and 25 which are rigidly secured thereto. The free end of the lever 13 is provided with a hook shaped dagger retainer 26 which, as shown extends through the dagger 24 and engages the lower face thereof with its hook shaped end. The daggers 24 and 25 pass to and fro abreast or above slidably mounted frogs 28 and 29 which are preferably mounted on frame members 27. Springs 30 are provided to return the frogs to their normal positions after the same have been released by the daggers. Then a shuttle has acted upon the picker (not herein shown or described) to force the picker bar t into its extreme left position as shown in Fig. 2, then the roller 17 engages the incline 15 and depresses the cam end of the lever 13 thereby raising the opposite end whereby the shaft 23 is rocked by the dagger retainer 26 to retain or lift both of the daggers 24 and 25 out of engaging proximity to their frogs on the forward or filling movement of the lay. It may be noted that a spring 31, connected with the lay sword, and with a collar 32 on shaft 23, normally acts to move the daggers into an engaging position with their frogs, the lever 13 acting against the resistance of this spring. If the shuttle fails to move the picker bar a to its extreme left hand position, then the roller 17 engages the lower cam portion 1 1, of the lever 13, and the spring 31 is free to hold the daggers in a position to engage their frogs because the free end of the lever 13 is not raised. l/Vhen the daggers engage beam 39. The slot 37 is provided with what may be termed an operating shoulder 40 and a non-operating shoulder 41, against which the shipping handle is engaged when in such respective positions, that is, when in a position to operate the loom and when in a position to throw the loom out of operation, respectively. The operating connections whereby the shipping handle throws the loom into and out of operation do not form a part of this invention and are therefore notherein shown and described.

My invent-ion also includes means for throwing the loom out of operation when the shuttle fails to reach or attain an extreme right hand position in the nonchanging or free shuttle box 20. For this purpose the shuttle box 20 is provided wit-h a swell 42 which is pivoted at as and is normally thrust inwardly partially into the path of the shuttle by an arm 44 mounted upon rock shaft 23. Inasmuch as any form .of swell may be used it has not been thought necessary to illustrate sectional views, in addition to the elevation shown in Fig. 2. It will be understood that if the shuttle does not reach an extreme right hand position in the free or non-changing shuttle box 20, there will be lost a motion of the corresponding picker bar (not shown) from its normal outward position to its point of engagement with the shuttle, therefore, the impact of its picker with the shuttle would not be suificient to drive the shuttle toward and fully into the shuttle-changing box 19, at the opposite end of the lay. It will thus be seen that it is just as necessary to throw the loom out of operation when the shuttle does not reach a proper position in the box 20 as it is when the shuttle does not reach'a proper position in the box 19. It is well known that when a shuttle is not driven completely through the shed of warp that the filling or beating movement of the lay would jam the shuttle into the point of convergence of the shed, in a fixed or fast reed loom, and thereby break the warp, this being not so in a loose reed loo-m because the reed of such a loom would yield to prevent such damage.

The protecting mechanism herein shown is also adapted for use in connection with a loose reed loom wherein the loom is thrown out of operation by an ordinary dagger and bunter mechanism.

I claim:

1. In a loom, in combination, a swinging lay, a dagger and frog mechanism associated therewith, a picker bar, and a rocking bar provided with a cam engaged by the picker bar for preventing and causing operative coaction bet-ween the dagger and frog.

2. In a loom, in combination, a swinging lay, a dagger and frog associated with the lay, a' picker bar provided with a roller, and a rocking bar having a cam portion engaged by said roller for preventing and causing ope 'ative coaction between said dagger and frog.

3. I11 a loom, in combination, a swinging lay, a dagger and frog, a picker bar, and a rocking bar having a cam engaged by the picker bar and connected with the dagger for preventing and causing operative coaction bet-ween the dagger and frog.

at. In a loom, in combination, a swinging lay, a. dagger carried by the lay, frog arranged in the field of movement of the dagger, and a rocking bar having a cam engaged by the picker bar and connected with the dagger for preventing or causing operative coaction between the dagger and the from 5. In a loom, in combination, a swinging lay, a rock shaft mounted thereon, a dagger carried by the rock shaft, a frog arranged in the field of movement of the dagger, a picker bar, and a rocking lever connected with the dagger and provided with a cam adapted for engagement by the picker bar for preventing and causing operative coaction between the dagger and frog.

6. I11 a loom, in combination, a swinging lay, a dagger and frog associated therewith, a shipping handle associated with said dagger and frog, a picker bar, and a rocking lever provided with a cam engaged by the picker bar for preventing or causing operative coaction between the frog and dagger to shift said shipping handle.

7. In a loom, in combination, a swinging lay, a dagger carried thereby, a slidably mounted frog in the field of movement of said dagger, a shipping handle for said loom operatively associated with said frog, a

picker bar, and a rocking lever provided witha cam engaged by the picker bar and connected with said dagger for causing and preventing operative coaction between the dagger and frog, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
